Relaxing whilst doing Competition Law is not an Oxymoron

Market Definition Teasers

with 3 comments

Following Alberto Alemano’s comment a few days ago, I’d like to ask our readers to share possible ” market definition teasers“.

The concept covers funny AND intricate market definition examples. In other words, market definition illustrations which can be used with students approaching the issue for the first time.

Here are mine, centered on products placed on relevant markets with possibly fluctuating borders :

  • Coca-Cola & Pepsi & other drinks
  • Eurostar & Ferry & Airlines
  • Personal computers & Macs
  • Branded fragances v. non branded fragances
  • iPhones & other mobile phones
  • Inux & Windows
  • Theatrical movie distribution & DVD rental distribution
  • CD-recorded music & digital music files
  • Low costs carriers & flag carriers

PS: The picture above is taken from Puggy’s latest album. This LP – which includes a song entitled teaser – is terrific.

  1. Nice post!

    Just a few thoughts :

    – short messages (SMS & email)

    – Internet services (3G ones & wifi based ones)

    – Theatrical movie distribution, DVD rental distribution + Video On Demand VOD

    – Computer softwares & mobile phone apps

    – Flag carriers, low-cost carriers and… bus services (under special weather conditions or due to seismic activity influence)

  2. The following example is not exactly related to your question, but still it may be interesting to present it in a class as a peculiar example of market definition’s scope in antitrust cases:
    “It is undisputed that casinos mix and match products to maximize floor-space revenue generation,” the judge wrote. “By limiting the relevant market to ‘wheel games,’ the court would not be including all reasonably interchangeable products in the market.” And since there was no relevant market, Jones concluded, Bally’s antitrust case couldn’t proceed.

  3. I guess that convergence will soon result in the creation of one big maket for smartphones and tablet PC. The question is: when ?
